Method, device and system for managing virtualized network function network elements

Abstract

Provided in an embodiment of the present invention are a virtual network function (VNF) network elements management method, device and system, the method comprising: a VNF resource pool management device receives a VNF network element request message transmitted by a VNF resource pool user (PU), the VNF network element request message comprising the attribute information and position strategy of a VNF network element to be requested; according to the VNF network element request message and the position information of the VNF network element in a VNF resource pool, the VNF resource pool management device determines a first VNF network element conforming to the attribute information and the position strategy from the VNF resource pool, the first VNF network element comprising at least one VNF network element; and the VNF resource pool management device transmits to the VNF resource PU a VNF network element response message comprising the identifier information of the first VNF network element, thus avoiding the risk of abnormal operation of a functional group constituted of the VNF network elements.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a management method, device and system for virtualized network function network elements. Background technique [0002] At present, major operators pay more and more attention to virtualized network functions (Virtual Network Function, VNF for short). VNF includes the virtualization of L3 functions and the virtualization of L4-L7 functions. The virtualization of L3 functions may include: virtual provider edge equipment (virtual Provider Edge, vPE for short), virtual broadband network gateway (virtual Broadband Network Gateway) , referred to as: vBNG) and virtual data center gateway (virtual Date Center Gateway, referred to as: vDC GW), etc., the virtualization of L4-L7 functions can include: virtual load balance device (virtual Load Balance, referred to as: vLB), virtual WAN optimization Controller (virtual Wan optimization Controller, referre...

Problems solved by technology

[0004] However, if at least two VNF network elements constituting a functional group run on the same VM or the same Hypervisor or the same server, when the VM or the Hypervisor or the server fails (also known as the risk sharing problem), it will Make the functional group composed of these VNFs not work normally
